WASHING APPARATUS.

Specification of Letters Patent.

Patented May 2c, 1908.

Application filed February 6, 1908. Serial No. 414,584,

To all whom it-may concern:

Be it known that I, FREDRIOH screens, a citizen of the United-States ofAmerica, residing at Hi 'hland,in the county of Madison and State 0#IIIIIIOIS, have invented certain new and useful Improvements in WashingApparatus, of which thefollowing is a full, clear, and exactdescription, reference being had to the accompanying drawing, formingpart of this specification.

My invention relates to an apparatus for,

use in washing sand and other materials.

Figure I is a vertica longitudinal section taken through my apparatus.Fig. II is an end elevation looking at the delivery end of' theapparatus. Fig. III is a vertical cross section taken on li. a III.-III,Fig. I.

In the accompanying drawings: 1 desig v nates a revoluble drum that isrovided at its receiving head or end A with an inlet opening 2preferably surrounded by an annular flaring flange 3. The drum also hasat its delivery head or end B, an outlet opening 4. Within the drum andextending longitudinally thereof are. angular flights 5 that areinclined from the. receiving end of the drum to the delivery-end of thedrum andrelative to its axis.

position to the heads or ends of the drum and which serve as supportsfor bearing boxes in which are mounted shafts 7 on which are arrangedrollers 8 serving as supports on which the drum'l turns. One of theshafts 7- has fixed to it a drive-pulley or wheel 9 to which posver maybe transmitted, and also a pinion .10 that meshes with a'cylindricalrackjll fixed to thedrum to provide for the rotation of-sa1d drum.

I 12 designates a pair ofsupporting bars thatare fixed at their ends tothe end frames f6 andextend longitudinallythrough the drum 1.

' 13 are receiving chutes of broadscoop shape and of whichthere'is aseries, attached to the supporting bars 12".withinthe drum.

and inclined" forwardly t ward the delivery "end 'ofthe drum."' Thelower free ends of these chutes terminate above'the bottom of .to'th'edrum' fso that. said 'drurn' may revolve a material is finally 6designates end frames located in juxtafreely around the chutes. 14 is adischarge chute of broad scoop shape that is supported by the supportingbars 12 in front of the most forward chute 13, and which extends throughthe outlet opening 4 of the drum.

In the practical use of'my washing appar ratus, the sand or othermaterial to bewashed is introduced into the drum 1, through itsinlet 0ening in any suitable manner, such as by s oveling it through saidopening or. extending a conveying chute through the opening, and wateris conducted into the drum at I its delivery end through a pipe 15, (seeFigs. I and II). The drum being set in motion, the material placedtherein is elevated by the angular flights 5 at the interior of the drumand when the material is carried to a position above the rearmost chute13, it descends into said chute and moves forwardlytherein, due to theinclination of the chute, to fall at the bottom of the drum at a pointnearer the delivery end than that at which it was elevated. The materialis again picked up by the flights and emptied into the next succeedingchute .13 to move forwardly as it descends from said chute, and thisaction is continued throughout the extent of the drum until thedischarged from the a aratus through t e delivery chute 14. l ue to theflights 5 being inclined as mentioned, the material is in part carriedforwardly by said flights and is prevented from moving backwardl in thedrum alon the flights. The water eing delivered into the drum at itsdelivery end supplies all of the needs for the washing of the materialwhile it is being conducted through the apparatu's'and further providesfor the discharge of dirty water through the receiving end of theapparatus over the annular flaring flange at which the material isintroduced, so that the water at the delive end is kept in a muchcleaner condition t an it would be, if the water were introduced at thereceiving end.

I claim:

A washing apparatus comprising end frames, a pairof longitudinalsupporting bars fiX'edat their'ends to the end frames, a

series of inclined broad scoop-shaped chutes securdto and depending fromthe supportioo- ing bars, an inclined broad scoop-shaped wardlyextending flights extending from end chute seoured to and depending fromthe to end of the drum; the drum being mounted supporting bars, andprojecting through the on the rollers and surrounding the chutes.
